Ecological drought for sagebrush seedings in the Great Basin Ecological drought for sagebrush seedings in the Great Basin
Monthly Standardize Precipitation Evapotranspiration Index (SPEI), Daily soil-water potential (MPa) and soil temperature (degree C) data for plots from SageSuccess. The SageSuccess Project is a joint effort between USGS, BLM, and FWS to understand how to establish big sagebrush and ultimately restore functioning sagebrush ecosystems. Improving the success of land management treatments to...
Simulated Soil Water Potential in National Parks and Monuments of the Southern Colorado Plateau, 1915-2099 - Data Simulated Soil Water Potential in National Parks and Monuments of the Southern Colorado Plateau, 1915-2099 - Data
These data were simulated using the SOILWAT model and were intended to characterize soil-water conditions at different ecological sites on the Southern Colorado Plateau. SOILWAT is a daily, site-specific, multi soil-layer, ecosystem water-balance model, driven by daily meteorology, as well as site soil texture and vegetation. The sites simulated correspond with Inventory and Monitoring...
Long-term Experimental Forest Growth and Drought Data Long-term Experimental Forest Growth and Drought Data
These data were compiled in order to represent long-term (multi-decadal) forest growth across eight different experimental forests in the United States, each with replicated levels of density treatments, as well as an important drought index correlated to growth. Forests around the world are experiencing severe droughts and elevated competitive intensity due to increased tree density...

Are drought indices and climate data good indicators of ecologically relevant soil moisture dynamics in drylands? Are drought indices and climate data good indicators of ecologically relevant soil moisture dynamics in drylands?
Droughts are disproportionately impacting global dryland regions where ecosystem health and function are tightly coupled to moisture availability. Drought severity is commonly estimated using algorithms such as the standardized precipitation-evapotranspiration index (SPEI), which can estimate climatic water balance impacts at various hydrologic scales by varying computational length...

Tree mortality response to drought-density interactions suggests opportunities to enhance drought resistance Tree mortality response to drought-density interactions suggests opportunities to enhance drought resistance
The future of dry forests around the world is uncertain given predictions that rising temperatures and enhanced aridity will increase drought-induced tree mortality. Using forest management and ecological restoration to reduce density and competition for water offers one of the few pathways that forests managers can potentially minimize drought-induced tree mortality. Competition for...

Non-analog increases to air, surface, and belowground temperature extreme events due to climate change Non-analog increases to air, surface, and belowground temperature extreme events due to climate change
Air temperatures (Ta) are rising in a changing climate, increasing extreme temperature events. Examining how Ta increases are influencing extreme temperatures at the soil surface and belowground in the soil profile can refine our understanding of the ecological consequences of rising temperatures. In this paper, we validate surface and soil temperature (Ts: 0–100-cm depth) simulations in...

Landscape‐scale restoration minimizes tree growth vulnerability to 21st century drought in a dry forest Landscape‐scale restoration minimizes tree growth vulnerability to 21st century drought in a dry forest
Increasing aridity is a challenge for forest managers and reducing stand density to minimize competition is a recognized strategy to mitigate drought impacts on growth. In many dry forests, the most widespread and common forest management programs currently being implemented focus on restoration of historical stand structures, primarily to minimize fire risk and enhance watershed...

Low stand density moderates growth declines during hot droughts in semi-arid forests Low stand density moderates growth declines during hot droughts in semi-arid forests
Increasing heat and aridity in coming decades is expected to negatively impact tree growth and threaten forest sustainability in dry areas. Maintaining low stand density has the potential to mitigate the negative effects of increasingly severe droughts by minimizing competitive intensity.However, the direct impact of stand density on the growing environment (i.e. soil moisture), and the...
